You may see a few different kinds of oats in the grocery store, including steel-cut, rolled, quick or instant. Steel-cut oats, also called Irish oatmeal, are the whole oat kernel that has been cut into two or three pieces using steel disks. 

This type of oats contains the highest amount of fiber, as it is least processed. Steel-cut oats take a little longer to cook, and result in a creamy and chewy porridge. Steel-cut energy oats can be made in a slow cooker, making the process less hands-on. 

Eating oatmeal regularly can have weight management benefits as a half-cup of rolled oats cooked in a cup of water has 165 calories, 4 grams of fiber and 6 grams of protein. The fiber and protein content contribute to feeling full longer and a slower blood glucose release.,gut%20bacteria%20and%20intestinal%20health.
